Definitions

  • the invention is in the field of SZ stranding of stranding elements of electrical cables and wires and aims to reduce the influence of the reversal points of the twisting direction of the stranding elements on the mechanical and / or electrical properties of the stranded material.
  • SZ stranding is used today for combined pair, triple or star-quad basic bundle stranding of communication cables as well as for stranding with subsequent sheathing of multi-core, permanent power cables with conductor cross-sections up to 2.5 mm 2 .
  • SZ stranding can be considered wherever a stranding process and another work step can be combined.
  • this also applies to the covering of flexible elements in combination with a further operation, for example for the stranding and subsequent sheathing of the wires of flexible lines, the conductors of which consist of wire strands, or for the stranding of stranded conductors and the subsequent application (Extrude) the insulation.
  • Such flexible lines are, for example, core lines, connecting lines for household appliances and connecting cords for telephone sets.
  • the SZ stranding of the stranding elements is generally carried out with the aid of storage devices in which the stranded material combined into a strand is stretched and which consists of a first stranding point arranged at the entrance of the storage device, for example a stranding nipple, and a second , at the output of the storage device arranged stranding point (for example a stranding nipple or a deflecting roller) and each consisting of a rotatable stranding head arranged immediately behind the first stranding point and immediately before the second stranding point.
  • storage devices in which the stranded material combined into a strand is stretched and which consists of a first stranding point arranged at the entrance of the storage device, for example a stranding nipple, and a second , at the output of the storage device arranged stranding point (for example a stranding nipple or a deflecting roller) and each consisting of a rotatable
  • the axes of rotation of the stranding heads lie in the stranding axis in which the stranding elements combined into one strand are also guided.
  • SZ stranding either the direction of rotation of the two stranding heads or, if the direction of rotation remains the same, only the speed of one or both stranding heads is changed at intervals which correspond to the throughput time of a cross-sectional element of the stranding material from the first stranding point to the second stranding point (DE-AS 15 15 730 , DE-PS 22 30 972).
  • the change in the rotational movement of the stranding heads is usually carried out periodically in two steps, i. H. the rotary movement alternates between counterclockwise and clockwise rotation or between a low and a high speed.
  • the distance between the entrance and the exit of the storage device and thus between the two stranding heads arranged at the exit and at the entrance about 2-10 m. Since the rotational movement of the stranding heads is changed at intervals which correspond to the passage time of a cross-sectional element of the stranded material through the storage device, the distance between the reversal points of the twist direction in the finished stranded material is also approximately 2-10 m.
  • reversal points of the twist direction represent both mechanical and electrical weak points because, on the one hand, the stranding elements can rope up in the area of the reversal points or because the flexibility of the stranding elements in the area of the reversal points is reduced and because the stranding elements in the area of the reversal points are arranged relatively untwisted to one another, so that there are particularly high electrical couplings in communication cables.
  • a number of measures are known which aim to reduce the negative effects of these reversal points while maintaining the aforementioned distance of the reversal points of the swirl direction, for example stranding the stranding elements in the area of the reversal points with a relatively short lay length or periodically spacing the reversal points by one To let the mean fluctuate.
  • the proposed constructive design provides that a winding body is arranged coaxially to the stranding axis and oscillating about it, on which the stranded material is arranged in a plurality of turns running around the stranding axis and to which guide members are assigned on both sides, one of which has the stranded material winds up the bobbin and the other unwinds the stranded material from the winding body.
  • the winding body itself is designed in such a way that the turn of the stranded material applied at one end can be transported along the winding body at the other end (DE-OS 16 85 842).
  • a stranded material produced with such a storage device in which the reversal points of the twist direction are at a large distance from one another, can be cut into short consumption lengths which have no reversal points of the twist seal.
  • the storage device provided for this purpose is very complex in terms of construction, its design with regard to the fixing of those points of the stranded material at which the winding direction of the storage element is changed appears difficult and the production speed should be relatively low.
  • the invention has for its object to design a SZ stranding machine for electrical cables and wires so that there are relatively large distances of up to 500 or 1000 m of the reversal of the twist direction in the finished stranded material at high production speed and a comparatively short overall length of the machine.
  • the originally straight-line storage section is divided into several sections, which are successively connected to one another by guides for deflecting the strand in such a way that an approximately accordion-like arrangement of the storage sections results.
  • the overall length required for large storage sections is reduced to a fraction.
  • the overall length of the storage device thus does not exceed, or only slightly, the overall length of other machine devices required for the production of electrical cables and lines.
  • a required storage distance of 100 m can be broken down into ten sections, each 10 m long, so that the overall length of the storage device is only 10 m, or a storage length of 240 m can be broken down into six sections of 40 m to be taken into account that the SZ stranding of stranding elements is often followed by a production step in which a covering is applied to the stranding elements by extrusion of a plastic and in which this plastic covering is subsequently cooled in a cooling device.
  • the commercially available cooling pools have lengths of 20 to 50 m, for example.
  • the storage device could therefore be arranged in parallel next to the cooling device without thereby increasing the overall length of the entire production device. This is especially true when the new stranding device is provided for stranding wires for hose lines, which are manufactured in large production lengths, but whose useful lengths are relatively short, so that the reversal of the twist direction in the finished line without much material loss or without large remaining lengths arise, can be cut out.
  • This can increase the effective storage length of the new SZ stranding device be that the rotary movements of the stranding heads, which rotate with the direction of rotation always constant, are not changed in just two steps, as was previously customary, but in at least two increasing and the same number of decreasing steps.
  • the distance between the reversal points of the twist direction present in the finished stranded material can hereby be increased to a multiple of the actual storage length of the storage device.
  • a uniform stranding of the stranded material is achieved if the speed difference between two successive steps is always the same.
  • three increasing and three decreasing steps when changing the speed of the stranding heads, i.e. with six steps within a stranding period the distance of the reversal points on the Increased three times the storage length of the storage device.
  • the stranding heads arranged at the entrance and exit of the storage device and the straight-line guides for the stranded material are arranged in different planes.
  • the linear guides it is advisable to arrange the linear guides in more than two parallel planes, the stranding head arranged at the entrance then being in the first level and the stranding head arranged at the exit being in the last level.
  • the stretched stranded material performs a rotating movement about its own axis.
  • the rectilinear guides provided in the new storage device and the guides for deflecting the strand must enable or effect such rotation of the stranded stranded material.
  • this can be achieved in that the inside diameter of the guides comprising the stranded material is larger than the stranded material, so that practically no forces act on the stranded material in the circumferential direction, or that the linear guides rotate with the stranded material about the stranding axis.
  • the straight-line guides can themselves be designed as rotatable stranding heads or consist of rotatable pipe sections.
  • a further stranding head can be arranged in front of and behind each guide in a further development of the invention, these further stranding heads with the at the entrance and stranding heads arranged at the output of the storage device can be rotated in the same direction.
  • the stranding heads can be viewed as straight-line guides or as part of the guides for deflecting the strand.
  • the actual deflection of the strand from one level to the next level, in particular to the next parallel level can take place with the aid of a single deflection disk or deflection roller, which can also be designed as a pull-off device.
  • the stranded material is largely roped when it runs onto the deflection pulley and roped again when the deflection pulley runs off, so that the stranded material has the same twist state in front of and behind the deflection pulley despite a brief interruption of its rotation and can continue its rotation after leaving the deflection pulley.
  • the transmission of the rotational movement of the stranded material and thus its state of twisting in the area of the guides for deflecting the strand can also take place in that, in addition to the guide surfaces of the linear guides, the guide surfaces of the guides for deflecting the strand in the circumferential direction of the strand which is constantly rotating about its axis thereon apply force-free or almost force-free.
  • Such a deflection of the strand can take place, for example, by means of a flexible hollow shaft which can be rotated about its own axis or by means of flexible hoses.
  • a guide which consists of three or more guide rollers arranged on a circular arc is also advantageous, it being ensured that the wrap angle of the individual guide rollers is not greater than 60 °.
  • a driven stranding head can also be arranged between the deflection rollers to maintain the rotational movement of the stranded material. If materials with a very low coefficient of friction are available, the guide for deflecting the strand can also consist of a skid.
  • a particularly advantageous embodiment of the guides for deflecting the strand is obtained if they consist of a plurality of rollers or rollers arranged on a circular arc and inclined relative to the guide axis.
  • a changeability of the angle of inclination is obtained, for example, by the fact that the axes of the rollers or rollers are fixed in space and articulated at one end and are displaceably mounted at their other end in the direction of the guide axis of the stranded material (DE-OS 24 58 353).
  • rollers or rollers are mounted in two circular rings containing the bearings, which can either be rotated independently of one another to change the inclination of the axes of the deflection rollers or deflection rollers or to change the local position of the rollers or rollers together un theirs Axis are rotatable.
  • Stranding machines are known per se in which the stranding elements are twisted in a double lay with the aid of a stranding bracket and in which the stranded material is deflected within the stranding bracket by a device through an angle of 180 °, which consists of several arranged one behind the other in the course of the stranding bracket, opposite the Guide axis of the stranded material inclined rollers or pairs of rollers.
  • a device through an angle of 180 °, which consists of several arranged one behind the other in the course of the stranding bracket, opposite the Guide axis of the stranded material inclined rollers or pairs of rollers.
  • the stranding heads arranged at the entrance and at the exit of the storage device and the further stranding heads arranged in front of and behind a guide for deflecting the strand in two mutually parallel planes one above the other and / or next to one another are arranged.
  • the storage capacity of the storage device is also determined by the distance between the two parallel planes in which the stranding heads are arranged. In the interest of the largest possible storage capacity, this distance should be more than 20 m, preferably more than 30 m.
  • FIG. 1 An embodiment of the new SZ stranding device is shown schematically in FIG. 1 together with two diagrams in FIGS. 2 and 3. Individual structural elements of the SZ stranding device are shown in the following FIGS. 4 to 14.
  • Fig. 1 shows a manufacturing device that is used to manufacture a flexible hose line by first stranding wires 1 to a stranding unit 2 and this stranding unit is then immediately further processed in the same operation by extrusion coating with a plastic jacket to line 3.
  • the cores 1 are stranded to form the stranding unit 2 with the aid of the SZ stranding device 4, while the plastic jacket is applied by means of the extruder 5 and the downstream water cooling device 6.
  • the SZ stranding device 4 is designed as a storage device with elongated guidance of the stranded material in the stranding axis. On the length section of the stranded material located within the storage device in each case a certain number of twisted strings are always stored, the final twisting state of the stranded material being determined when it runs out of the storage device.
  • the storage device initially consists of a first stranding point 10 arranged at the entrance in the form of a stranding nipple into which the wires 1 enter. Immediately behind it is a rotatable stranding head 11, with which the stranding elements are stranded together as they enter the storage device.
  • the second stranding point at the outlet of the storage device is formed by the take-off disk 8, i. H. the run-up point of the stranded material on the take-off device forms the second stranding point.
  • the second stranding head 12 Immediately in front of it is arranged the second stranding head 12, by the rotational movement of which the stranded material is given a second twist as it runs out of the storage device, which results in the final twisting when superimposed on the twisting achieved when it enters the storage device.
  • the stranding heads 11 and 12 are ver in two different, parallel planes a and d arranged. In these planes, as well as in the parallel planes b and c, straight guides 13 for guiding the stranding elements combined to form a strand 19 are arranged. Between the individual levels, guides 14 are arranged for deflecting the strand 19 through 180 ° from one level into the next level. By means of these guides for deflecting the strand, the strand passes through the entire storage device in the shape of an accordion or a serpentine shape. Each guide 14 for deflecting the strand is assigned two stranding heads 15 and 16, one of which is connected upstream of the guide and the other downstream of the guide.
  • the take-off device 8 serves at the same time as a device for deflecting the strand 19 from level d into the level of the water cooling device 6. Between the take-off device 8 and the extruder 5 arranged behind it, a known rope device 17 is arranged, with which possible arcing of the stranded material is eliminated. Between the extruder 5 and the downstream water cooling device 6 there is a marking device 18, with the aid of which the extruded jacket is marked at the points at which the reversal points of the swirl direction which arise during the stranding of the wires result. This marking device is controlled via the rotary movement of the twisting heads 11 and 12.
  • the stranding heads 11 and 12 are arranged together with the stranding heads 15 and 16 in two mutually parallel planes A and B. This makes it possible to drive the stranding heads arranged in levels A and B together using a single drive.
  • the distance between the two levels A and B together with the number of levels a to d determines the storage length of the storage device.
  • the distance between the levels A and B can be, for example, 40 m, the linear guides 13 being arranged at a distance of 10 m between the two levels. With four parallel levels a to d, this would result in a total storage length of 160 m.
  • the stranding of the wires is essentially determined by the two stranding heads 11 and 12. These rotate with a constant direction of rotation and changing speed. This ensures that no reversal points of the twist direction occur within the storage device, which could otherwise become stranded under the influence of tensile stresses and on the deflection devices.
  • the strand 19 located within the storage device can carry out the rotational movement imparted by the stranding heads 11 and 12 without hindrance.
  • the linear guides 13 and the guides 14 for deflecting the stranded material are to be designed accordingly.
  • the linear guides 13 In the case of a tubular design of the linear guides 13, they always rotate in the same direction of rotation, based on the stranding axis, as the stranding heads 11 and 12 and change their speed synchronously with the stranding heads 11 1 and 12, which are the same or approximately the same as the speed of the stranding heads 11 and 12 is.
  • the stranding heads 15 and 16 ensure that the strand 19 can also perform the required rotational movement about its own axis in the region of the guides 14.
  • FIGS 2 and 3 show that the speed n of the twisting heads at intervals of the SZ-twisting corresponding to the entire storage length 1 0 4, increasing in three and three decreasing steps is changed, wherein the step height of the individual steps is preferably chosen to be the same.
  • the speed n can be changed during the SZ period L in the steps 500, 1500, 2500, 3500, 2500, 1500, 500 rpm.
